## Overview

Booking-System is described as a system for booking classes using packages. The tree shows separate user, class-booking, package-management, authentication, and shared-domain modules. No source excerpts were provided, so the graph keeps relationships to the README’s broad product description and does not infer internal calls or runtime flow.

Main entry points: [`booking-package/src/main/java/com/example/booking/pack/api/PackageManagementApi.java`](https://github.com/tuntunhlaing/booking-system/blob/main/booking-package/src/main/java/com/example/booking/pack/api/PackageManagementApi.java) (Package API), [`booking-user/src/main/java/com/example/booking/user/api/BookingClassApi.java`](https://github.com/tuntunhlaing/booking-system/blob/main/booking-user/src/main/java/com/example/booking/user/api/BookingClassApi.java) (Class API)
